enable mod expire for fast image loading

here is the example from google (they have set the cache expire far far in the future )

$ curl -I

HTTP/1.1 200 OK

Cache-Control: public

Content-Length: 16715

here is my configure.nice script for apache 2.2.x

"./configure" \
"--prefix=/opt/apache2.2" \
"--enable-so" \
"--enable-mantainer-mode" \
"--enable-module=all" \
"--enable-rewrite" \
"--enable-include" \
"--enable-info" \
"--enable-expires" \

also after all is build and installed (apache server restarted)
you can check the expire config

$/opt/apache2.2/bin/httpd -l | grep expire

or in browser

and add the expire config into the httpd.conf or .htaccess

ExpiresByType text/html "access plus 1 month 15 days 2 hours"
ExpiresByType image/gif "
access plus 1 month 15 days 2 hours"

you can check later the expire headers with curl

$curl -I

Hello Mariuz.

I have a thing to say about the Firebird installation:


It worked just fine!

On the first time I've installed, I probably missed the part of the package configuration.

I'll pay more attention on my future installations and use more the Console than the visual package manager.

Once again, thank you so much.

ok then :)

i will put that part in red and bold

usually in my opinion it should be enabled by default , but damyan told me firebird 2.1 should be disabled after install , and it will be configured only when the user wishes to do so
